[quote author="SGaist" date="1405668675"]Hi, Doesn't Navit use GTK+/SDL for it's UI ? You should rather ask this question on their forum[/quote] Hi, Thanks for the reply. I think by default Navit is using "internal gui". I got this from navit.xml, "<gui type="internal" enabled="yes">". I found a link "here":http://wiki.navit-project.org/index.php/QML_GUI, and they are using "qml gui" instead of internal gui. I tried this, but i doesn't work for me. May be i will try in their forum to. Regards Ansif

Solved. It appeared I had a 64-bit NDK installed even though I thought I had downloaded a 32-bit NDK. I blew away all NDK remnants and downloaded new 32-bit r10 NDK and now my Android x86 emulator is launching my Qt hello world app. android-ndk32-r10-darwin-x86.tar.bz2 -Ed

That doesn't answer my question, what kind of gif is it ? What are the image characteristics ? A 60M file looks like a very big animated gif so it might not be the best format for such an animation. QMovie caches each frame of your gif in a format suitable for displaying. If you think it's not optimum you are welcome to improve the class.

Found it. "Input on linuxfb":http://qt-project.org/doc/qt-5/embedded-linux.html#configuring-for-a-specific-device

The solution for you problem is here: "http://www.qtcentre.org/threads/57352-QScroller-speed-and-touch-screen?p=265102#post265102":http://www.qtcentre.org/threads/57352-QScroller-speed-and-touch-screen?p=265102#post265102 Take a look in my post there. My QScroller is working fine now! Here is the Qt Code in case the link breaks: Try setting the verticalScrollMode of your view to ScrollPerPixel> @setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);@

ok I found the solution: in "build settings" from Xcode project in "Apple LLVM 5.1 - language - C++" section in "C++ standard library" line add "libc++" option thank's

I use bluetooth on Android, arm and i386 architectures without any problem. Bluetooth in not so easy to explain. I suggest you to look at the examples in Qt example subfolder. There are many steps, first pairing, second connect, third send and receive data...

OpenSSL on your device that is not the same ?

Hi, upgrading to 5.2.1 (previously it was 5.2.0) did the trick. I don't know what exact change resolved the issue, but well... cheers

You need to "Sign" the application: http://blog.qt.digia.com/blog/2014/03/26/qt-weekly-3-qt-for-android-tips-and-tricks/ Go down to the section "Signing the Application". Please note that there have been (and still are) some bugs to do so from Windows or Mac, however it seems to work in Linux.

Yeah, the problem is back, slightly different though. As you describe, the place where the statusbar was is now an empty whitish rectangle. See https://bugreports.qt-project.org/browse/QTBUG-39977

The Android emulator is far from perfect, it will not run smooth on PC's with slow CPU's. The deployment simply fails because the AVD is not booted, yet. Maybe try to set the API Level to 19, since 20 is not correctly recognized in Qt, yet afaik.

Hi, Unless you plan some heavy multithreaded concurrent access to the database, I don't see any reason not to use it.

Thank you for your guidance.
